Optical power meters are technical instruments used to measure optical signal, something which is key in testing average power in fiber optic systems.


Optical power meters typically consist of three basic elements. The first, a calibrated sensor, uses a photodiode used to measure wavelengths and power levels. The second, a measuring amplifier, is used alongside the calibrated sensor to verify accuracy and deliver data. The third, a display unit, provides the measured optical power and set wavelength for a technician to note.

In our experience, technicians have frequently combined GAOTek power meters with other functional test tools including optical light sources. The two primary uses of a GAOTek power meter is to measure absolute power in a fiber optic signal and to measure optical loss in a fiber in combination with a stable light source. Please note that a power meter should be properly calibrated to the wavelength being tested in order for the most accurate reading to be produced.

Support your fiber network with GAOTek power meters to test and measure optical power, certification capabilities, and for basic power measurements. Every day, our power meters are used by technicians in the field in the United States, in Canada, and globally. Using GAOTek power meters, receive highly accurate power measurements and test certainty regardless of test conditions.
